(Reuters) - An extensive ground search was under way on Friday for the missing pilot of a stealth fighter jet that crashed in a remote area of Alaska earlier this week during a nighttime training mission.

The pilot, identified as Air Force Capt. Jeffrey Haney, has not been heard from since his Lockheed Martin F-22 Raptor disappeared from radar as the aircraft and another jet were heading back to base at about 7:40 p.m. local time on Tuesday.
